Answer:

2.5m/s²

Force  = mass x acceleration  

Explanation:

Given parameters

Mass  = 200kg

Force  = 500N

Unknown:

Acceleration  = ?

Solution:

According to the Newton's second law of motion "the constant force applied on a massive body causes it to accelerate".

 Mathematically;

    Force  = mass x acceleration  

Now insert the parameters and solve;

   Acceleration  = \frac{force}{mass}  

   Acceleration = \frac{500}{200}   = 2.5m/s²

When exercising in the heat, which of the following hydration strategies is best for temperature regulation during an event (e.g
Olegator [25]

Answer:

Your question was incomplete so here is the complete question and answer.

Q. When exercising in the heat, which of the following hydration strategies is best for temperature regulation during an event (e.g., 10K race)

a) plain water

b) 5-7 percent glucose solution

c) Glucose polymer solution of 6-8 percent

d) There appears to be no difference among these different forms of hydration techniques relative to temperature regulation.

Ans. d) There appears to be no difference among these different forms of hydration techniques relative to temperature regulation.

Explanation:

Temperature Regulation is an important phenomenon for the person exposed to extreme hot conditions or weather. Exercising in hot conditions increase the body temperature. Greater and intense exercise, greater the production of heat. Then the heat dissipation takes place in the form of excessive sweating which results in dehydration. That was just the brief overview of temperature regulation. Above mentioned techniques are equally good hydration techniques so there is no difference at all. You can have a plain water or glucose solutions of above mentioned percentages.

What is the concentration of H+ ions at a pH = 7? mol/L What is the concentration of OH– ions at a pH = 7? mol/L What is the rat
AnnZ [28]
<h3><u>Answer;</u></h3>

= 0.0000001 mol/L  

= 0.0000001 mol/L  

= 1:1

<h3><u>Explanation;</u></h3>

What is the concentration of H+ ions at a pH = 7?

The formula for ph is given by:

pH=−log10[H+]

In calculating for the concentration of hydrogen ion, the formula is given by:

[H+]=(10)^(-pH)

Therefore; at pH = 7

[H+]=(10)^(-7)

<u>= 0.0000001 mol/L </u> 

What is the concentration of OH– ions at a pH = 7?

pH+pOH=14

7+pOH=14

pOH= 7

[OH-]=(10)^(-pOH)

[OH-]=(10)^(-7)

<u>= 0.0000001 mol/L  </u>

What is the ratio of H+ ions to OH– ions at a pH = 7?  

1:1

From the given υ – t graph, it can be inferred that the object is
laila [671]

Answer:

a) in uniform motion

Explanation:

When velocity-time graph is parallel to x-axis, it shows that the object is moving with constant velocity. or we can say that that the object is moving with uniform motion. There is no change in velocity. It covere equal distance in equal intervals of time.

Hence, the correct option is (a) "in uniform motion".
